Detailed Description

The WorldFrame class is a class that is used internally to create the singleton World Frame.

This class cannot be instantiated directly: you must use the Frame::World() function to access it. Only one World Frame exists in any application.

bool dart::dynamics::Entity::isQuiet ( ) const

inherited
